ASTM D3585-08(R2020) pdf free download.Standard Specification for ASTM Reference Fluid for Coolant Tests
1. Scope
1.1 This specification covers a reference ethylene glycol- base test fluid to be used in providing base line data for ASTM coolant test procedures. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro- priate safety, health, and environmental practices and deter- mine the applicability ofregulatory limitations prior to use. 1.3 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Chemical Composition Requirements
3.1 The reference test fluid concentrate shall be prepared to conform to the requirements as to chemical composition prescribed in Table 1.
4. Ingredient Requirements
4.1 The materials used to prepare the reference test fluid shall meet the requirements given in Annex A1 – Annex A5.
5. Significance and Use
5.1 The data obtained for the reference test fluid are intended to be used by laboratory personnel to determine their capability to perform tests properly. If a particular determina- tion does not fall within the prescribed limits, it has to be assumed that an error occurred in the application of the test procedure. 5.2 The coolant composition given in this specification is not intended to be a commercial product.
6. Chemical and Physical Requirements
6.1 The formulated reference test fluid concentrate shall conform to the requirements for physical and chemical prop- erties prescribed in Table 2.
7. Performance Requirements
7.1 The formulated reference test fluid concentrate shall conform to the requirements for laboratory test performance prescribed in Table 3.
8. Sampling
8.1 To obtain a sample of the concentrated reference test fluid from the storage container, allow the material to come to room temperature (not below 68 °F (20 °C)) and shake well before withdrawing the sample. 8.2 All aqueous solutions to be used for test purposes shall be prepared in accordance with Section 5 of Practice D1176.
9. Mixing Procedure
9.1 Weigh the ingredients according to the batch size required. 9.2 Mix the ethylene and diethylene glycols. 9.3 Dissolve the sodium tetraborate in the glycol mixture using continuous agitation.9.4 Dissolve the trisodium phosphate in the above solution. 9.5 Add the sodium mercaptobenzothiazole solution and continue agitating the mixture until it is homogeneous. 9.6 Slurry the dye into a convenient portion of the solution; then add the dye slurry solution back into the formulation. 9.7 Add the Pluronic L-61 antifoam and mix thoroughly. 9.8 Determine the water content of the formula in accor- dance with Test Methods D1123 and adjust to 4.0 6 0.2 mass % by the addition of distilled water.
10. Precision and Bias
10.1 For statements on the precision and bias of the various test methods for physical and chemical properties used in this specification, refer to the appropriate ASTM standards. 10.2 For statements on the precision and bias of the perfor- mance tests used in this specification, see the footnotes to Table 3. 10.3 It should be noted that the requirements listed in Table 2 on physical and chemical properties, and in Table 3 on performance, are based on the results of many different laboratories testing the same batch of reference test fluid.
11. Packaging and Storage
11.1 The test fluid concentrate may be affected by light. Therefore, after preparation, it should be packaged in opaque plastic containers or plastic lined metal cans. 11.2 Solutions prepared for testing should also be stored in opaque containers or kept in a cool, dark place to prevent the formation of flocculent precipitates. 11.3 Except when taking a sample, containers should be closed to avoid absorption of moisture from the air.
